SWITCH CONSTRUCTON.

Application led 'June 5,

My invention relates to switch construetion and more particularly to atipping button switch construction of the type used i'or controllingautomobile horns.

@ne ot the objects ot my invention is to provide an improved switchconstruction of this type which will be simple, durable, cheap andeiiicient.

Further objects will appear from the description and claims.

1n the drawings, in which two embodiments of my invention are shown-Figure 1 is an axial section;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 isa bottoin'view of the switch base;

Fig. L1 is a section on th-e line 1 1 of Fig. 2;

Fig. 2; and

Fig. 5 is an axial section showing another form ot switch mounting.

Referring iirst to Figures 1 to 5, inclusive, the construction showntherein comprises an insulating base 10, a pair of wiring terminals 11and 12 mounted on said base, .an annular switch contact` 13 `mounted ons'aid base, an insulating tipping button 111, a switch contact plate 15mounted on said tipping button and cooperating with the annular contact13, and means tor yieldingly supporting said tipping button on saidinsulating base and electrically connecting said binding terminals withsaid switch contacts, respectively.

The tipping button is .supported in its tipping movement by a hollowpost or eyelet 16 and a. coil compression spring 17 mounted in saidhollow post and pressing` upwardly on the tipping button, tending tohold the contact plate 15 in engagement with the outwardly extendingannular flange on the hollow post. The hollow post is riveted to a metalstamping 18, which .stamping is secured on the insulating' base by meansof the screw 19. The lower end of the post is reduced as indicated at 2Owhere it extends through the stamping and this reduction torms ashoulder on which the lower end of the spring 17 is seated. The contactplate 15 is held in place on the tipping button by a pair of eyeletmembers 21 imbedded in the insulating button and riveted over thecontact plate.

For holding the annular contact member 5 is a section on the line 5 5 ofFig.

1924. Serial No. 713,631.

13 on the insulating base 1() and insulating and positioning the metalstamping 18 and the post 16, an insulating washer 22 ot iiber or oth-cr.suitable material is provided which is clamped underneath the metalstamping engages .a loop or strap portion 25 entend ing downwardly andinwardly from the ,an--

nular contact member, the `toot portion 2'? of which strap liesunderneath the head of the screw. This screw 25 is threaded into thebinding plate 28 ot the wiring terminal 12. For electrically connectinglthe binding plate 29 of the wiring terminal 11 with the stamping 18 andfor securing the binding plate and stamping on the insulating base 10the screw` 19 is provided'which ext-ends through the binding plate 29,insulating base 10, and liber washer 22 and is threaded into thestamping, as shown in Figs. 3 and 1.

For holding the insulating bas-e 10 in place on the support 3() (whichmay be the spark lever ot the automobile) a pair o't screws 31 areprovided which extend through the support and insulating base 1() andare providedwith nuts 32 at their upper ends.

The circuit is from the binding plate 29 through the screw 19, stamping18, hollow post 16, contact plate 15, annular contact 13, loop 26, andscrew 25 to the binding plate 28.

The insulating washer 22 serves to position and center the inet-alstamping 18 and tubular post 16, an aperture being provided in theinsulated washer for this purpose, which receives thel lower end of thehollow post or eyelet asrindicated at 83 in Fig-s. l, 11 and 5.

The construction sho-wn in Fig. 6 is substantially the saine as thatjust described, except that here the insulating base 34 is seated in acuplilre housing portion 35 formed with. the spart; lever and kul saidpost.

is held in place in this cup-like housing by means of a screw 36extending through the side of the housing and threaded into a metalstamping 37 which is clamped underneath the insulating washer 22 andthereby held on the insulating base 34.

In operation, to sound the horn, the button 14 may be pressed at anypoint, causing some part of the contact plate 15 to engage the annularContact 13 to close the circuit. Y

lhile I have shown but two forms of my invention7 it is obvious that itmay be embodied in other forms covered and defined by the append-edclaims. n

Iilaving thus described my invention, what I elaiin as new anddesire tosecure by Letters Patent oi? the United States is :f-

1. A tipping button switch construction comprising afbase, a hollowcentral post on said base, an insulating Ybutton tiltably mounted onsaid post, a Contact carried by said button, and a eoil compressionspring mounted in said hollow post tor holding said button in operativetilting relation with respect to said post.
